Specification of Letters Patent.

Patented July 12, 1921.

Application filed December 8, 1919. Serial No. 343,268.

To all whom it may con-corn:

Be it known that I, REUBEN A. SIVARD, a citizen of the United States, residing at Oklahoma city, in the county of Oklahoma and State of Oklahoma, have invented certain new and useful Improvements in Violins, of which the following is a specification, reference being had to the accompanying drawings.

An object of the invention is to provide a violin which will be more durable and can be more easily and cheaply manufactured than violins heretofore produced.

Other objects and advantages of the'invention will be set forth in the ensuing description.

Referring to the accompanying drawings:-

Figure 1 is a front View of a violin embodying the principles of the invention.

Fig. 2 is a view of the lower or war end of the instrument,with the tail-piece, bridge, strings, and neck omitted.

Fig. 3 is a side elevation, with the tailpiece, bridge, strings, and head omitted.

Fig. 4 is a fragmental back view of the parts shown in Flg. 3.

Fig. 5 is an enlarged sectional view taken on the line 5-5 of Fig. 1, showing only the body of the instrument.

Fig. 6 is a sectional view taken on the line 5-5 of Fig. 1, but showing the body construction of the old-style violin.

Like characters of reference designate like parts in all the figures.

The tail-piece 7, bridge 8, finger'board 9, neck 10, and head 11 of the new instrument are not materially different from those heretofore used on violins.

In cross-section on theline 5-5 of Fig. 1, or on any other line, the front 12 and back 13 of the new instrument do not materially differ from the front and back of the violin as used for over one hundred years, the

regulation 8 holes being retained in the present instrument; but the pro ecting points 1 1 on the edges of the front and back i of the old instrument, shown by dotted lines in Fig. 1, are dis ensed with.

The inventor oes, however, provide a bass-bar of improved form on the front 12 together with certain rib formations on the back 13, and these features will be more fully described later.

In carrying out the objects stated, the thin, curved side walls 15 (Fig. 6) commonly interposed between and glued to the front 12 and back 13 are dispensed with; the front and back being brought together on the line A-A (Fig. 5) and securely glued.

With the front 12 and back 13 brought together as described, the plane surfaces presented for forming the glue joint can be and are of much greater area and the joint is therefore much more durable.

No forms for bending and setting the side walls 15 are required, the construction is cheaper, and the instrument as a whole is stronger.

As shown in Fig. 5, the bass-bar 16 of the new instrument extends integrally from the front 12 to the meeting line or plane AA, and as shown in Fig. 4 said bassbar extends the full length of the interior of the body.

This arrangement of the bass-bar forms a better truss for the front 12 against the acting of the bridge 8, and, from actual re sults obtained, seems to improve the tone of the instrument.

To arrange a proper anchorage for the neck 10, the back 13 is formed with an integral enlargement 17 which extends rearward at least to the line of total thickness of said back as shown in Fig. 3; this enlargement being as wide as said neck and extending with a diminishing taper downard to the point 18 of full total thickness of the back.

This enlargement 17 forms a good base for anchorage of the neck 10, since it takes hold of a greater and lower portion of the back 13 and cannot be torn out by the leverage of the neck.

In setting the neck 10 in place, it is abutted squarely against the upper ends of the front 12 and back 13 and against the inte gral enlargement 17 of said back on the line 13-13, being securely glued to said parts on said line.

A back plate 19 is then glued to the rear plane surface of the base portion 20of the neck 10 and to the rear plane surface of the enlargement 17 aforesaid on the line C-G (Fig. 3), this plate firmly connecting said neck and enlargement and reinforcing the neck against movement in the direction of the arrow 21 under action of the strings 22.

For purpose of anchoring the tail-pin 23, to which the tail-piece 7 is hitched in all violins, the lower end of the back 13 is formed with an integral rearward enlarge- "IDGDt 24 into which said tail-pin is inserted.

This enlargement 24 extends with diminishing taper upward to the point 25 ot full total thickness of the back 1-3 so that it cannot be torn out of said back by the prying action of the tail-pin 23.

It is to be understood throughout this description that the front 12 and back 13 are her, 1919.

The following is claimed A violin including an arehed tront and arched back said front and back engaging each other on a meeting plane without the interposition of the usual side walls, the back being provided on its outer or rear surface with an enlargement extending from its upper end downward with diminishing 'aper to the point 0]? full total thickness of said violin, the outer or rear surface of the enlargement being in the same plane as the center ot the arch formed by the hack a necl: abutting the upper ends of said front and back and the upper end ot said enlargement and glued thereto, and a hack plate glued to said enlargement and neck.

lVit-ness my hand this 19 day of Novem- REUBIL A. SIVARD.
